Kahn’s Flying Huntsman 6×6 concept is the next best thing to a personal tank

The Mercedes-Benz G63 AMG 6×6 may be sold out, but if you’re looking for a post-apocalyptic off-roader, there’s a new option.

English coachbuilder and Land Rover tuner Kahn Design decided to do AMG one better, building a six-wheel version of the stalwart Defender.

Standing tall above most of the other cars at the 2015 Geneva Motor Show, the Kahn Flying Huntamsn 110 WB 6×6 concept is a Challenger tank to the G63’s Leopard.

The concept is based on Kahn’s Flying Huntsman 105 Longnose, so named because it was lengthened to accommodate a General Motors-sourced 6.2-liter LS3 V8.

With 430 horsepower, it’s a big improvement over the small diesel engines offered in most stock Defender models. Still, the American V8 is somewhat outgunned by the 5.5-liter, 536-hp unit in the G63 AMG 6×6.

The four-wheel drive system appears unchanged, although Kahn says the brakes and suspension have been upgraded.

This concept got stretched from both ends, though. In addition to lengthening the wheelbase for the bigger engine, the rear quarters gained 31.5 inches of real estate to house the third axle. Kahn says it tweaked windshield rake and lengthened the doors for easier access, too.

Kahn plans to put both the four- and six-wheeled versions of the Flying Huntsman into production, giving rich Land Rover fans an alternative not only to the G63 AMG 6×6, but also any potential production version of the G500 4×4² concept also being shown in Geneva.

Different body styles – including a pickup truck – and armored versions are also under consideration, so buyers will have their choice of Mad Max-worthy upgrades.
